The UK Brain Bank Network is an initiative, led by the "Brains for Dementia Research" cohort study, to establish a coordinated national network of UK brain tissue resources (banks) for researchers to use. The banks store post-mortem brain and central nervous system (CNS) tissue donated by the public for diagnosis and research into disorders. Advances in understanding genetics and many of the molecules that define brain function mean that more and more research questions can be answered from human brain tissue. Collection of samples and data across the following diseases: Alzheimer's disease (disorder), Asthma (disorder), Atrial fibrillation and flutter (disorder), Cerebrovascular disease (disorder),Complete trisomy 21 syndrome (disorder), Congenital anomaly of brain (disorder), Degenerative brain disorder (disorder), Dementia (disorder), Depressive disorder (disorder), Diabetes mellitus type 1, Diabetes mellitus type 2, Epilepsy (disorder), Fit and well, Huntington's chorea (disorder), Ischemic heart disease (disorder), Jakob-Creutzfeldt disease (disorder), Malignant neoplasm of brain, Malignant tumour of prostate (disorder), Malignant tumour of urinary bladder (disorder), Malignant tumour of breast, Malignant tumour of colon, Malignant tumour of lung, Malignant tumour of oesophagus, Malignant tumour of ovary, Motor neuron disease (disorder), Multiple sclerosis (disorder), Multiple system atrophy (disorder), Parkinson's disease (disorder), Progressive supranuclear ophthalmoplegia (disorder), Psychotic disorder (disorder), Spinal muscular atrophy (disorder), Vascular dementia (disorder).
